How is $PID obtained? It looks to me like the HUP is being sent to the
shell script somehow, that would explain why the shell prints "Hangup"
and cron mails that to you. But I can't see how that would happen
unless the code to get $PID is badly broken.
On further investigation it seems that the shell prints Hangup when one of
its children sets SIGHUP, not when it itself gets SIGHUP. Anyway, knowing
how PID is determined might be useful.

ok, so I'm very fussy about using too many processes when one fewer
would do. :-)
